    by admosferic you mean "naturally aspirated"? in that case i've seen them with both MAP and MAFF sensors, those most new cars seem to use MAP sensors. what do you drive?

    ı think the athmosferic cars used maff and ı never seen map sensor in athmosferic cars for examla 1 bar map sensor ıs it use 0.5 for pressure and use the other 0.5 for vacuum?it is not logical for me
    what is your ideas about this subject?
    thanks emre

    MAP sensors are used in all kinds of NA cars, like Honda. All it does is convert the pressure in the intake manifold to a voltage signal for the ECU. I think they're a more robust design than the MAF sensors found in Nissans.

    Splitting a 1 bar map sensor in half for vacuum and boost doesn't make any sense. That would make it into a 0.5 bar map sensor.

    but you said that used in all cars ı dont see in athmosferic cars they measure the pressure in the athmosferic cars there arent any presura there are onl vacuum so they use maff sensor it is very usefull for vacuum theother side of map sensor is ıt can be measure the vacuum for example 3 bar map sensor measures 2 bar presure and 1 bar vacuum

    MAP sensors measure absolute pressure so just like air pressure is 101.kpa or 1 bar. A 1 bar sensor measures up to atmosphic pressure. a 2 bar sensor measures up 1 bar overpressure and a 3 bar measures up to 2 bar overpressure
